I just discovered something. I seem to have a different frequency response in my left and right ear.
I noticed that one side felt different/louder, so tried panning a Minitaur droning note left and right… At first I thought it was the headphone out on my old Mackie 1604. But I recorded the headphone out of the mixer into audacity, while turning the panning knob on the mixer back and forth. And when listening, i realised that it sounded the same, whilst looking at the L and R waveforms, they looked like mirror images.
So I swapped the headphones around (the L can on right ear etc) - and the experience was the same, i.e. bottom end gone on my right ear! Maybe this is a known thing? Hadn’t noticed it before. Any others with that experience? chances it can improve?
